BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.
1 to 8 show a first embodiment of a multi-stage rack unit device 2 (2A) using belt fittings K. FIG.
In FIGS. 1 and 6 to 8, the multi-level rack unit device 2 (2A) is configured by vertically stacking two reverse nester rack units R to form a multi-level rack unit R. A belt mounting bracket K having a headed pin 5 projecting from the front surface is attached to the left and right strut members 3, the right upper headed pin 5 and the left lower headed pin 5 are connected by a first belt B1, and the left left headed pin 5 is connected. and the right lower head pin 5 are connected by a second belt B2.

In the rack unit R, a lattice member is fitted in the frame to form an upper frame U in the shape of a square frame. The other end (lower end) side of the four strut members 3 is connected by a lower frame D, and the lower frame D connects the side rails 12 that connect the two front and rear strut members 3 on the left and right and the back side. It has a rear crosspiece 12 that connects the two left and right strut members 3, and the front opening Q is formed without the crosspiece 12 between the two left and right strut members 3 on the front side. This front opening Q serves as a loading port of the rack unit R. As shown in FIG.

In FIGS. 6 and 7, the cargo N exemplifies the goods placed on the pallet.
The left and right support members 3 on the far side are located directly below the corners of the upper frame U. The two front left and right strut members 3 are located outside the corners of the upper frame U, and their upper ends protrude upward from the upper frame U, and the hollow of the square pipe is open to form the upper front strut member. The lower end of 3 is formed to engage in the square pipe.

The rear part of the upper frame U is provided with a positioning member 17 with which the lower end of the upper rear support member 3 abuts.
Further, the rack unit R is provided with receiving members 18 on the front and rear sides of the upper surfaces of the left and right side rails 12 so that the left and right side rails 12 of the upper rack unit R can be supported when not in use. The structure allows the front support member 3 and the upper frame U of the upper rack unit R to be nested with respect to the lower rack unit R when not in use.

When the rack units R are stacked vertically in two stages, the rear rail 12 of the upper rack unit R is placed on the rear portion of the upper frame U of the lower rack unit R, and the rear portion of the upper frame U and the rear rail 12 are placed. A vertical connector P is provided to connect the . The upper/lower connector P has a fitting member 14 fitted to the rear part of the upper frame U and the rear rail 12, and a fastener 15 such as a bolt for fastening the fitting member 14. As shown in FIG.

1 to 8, the belt mounting bracket K for connecting the first belt B1 and the second belt B2 to the rack unit R consists of a fitting member 4 fitted to the support member 3 and a front surface of the fitting member 4. A headed pin 5 projecting from the fitting member 4 and a fastener 6 passing through the rear portion of the fitting member 4 .
Since square pipes are used for the strut members 3, the fitting member 4 has left and right side walls 4b extending rearward from both left and right ends of the front wall 4a, and has a substantially U-shaped shape in plan view. When a round pipe is used for the strut member 3, it is preferable to form the front wall 4a of the fitting member 4 in a semicircular or arcuate shape.

Rear portions of left and right side walls 4b of the fitting member 4 protrude rearward from the support member 3. Through holes 8 are formed in the rear portions, and fasteners 6 are inserted into the through holes 8 from left and right outside.
The fastener 6 is composed of a pair of threaded members 6a and 6b, and has a female and male screw connection structure. One threaded member 6a has a flange portion a and a hexagonal hole b at its outer end, and a male thread c at its inner end portion. and a hexagonal hole b, and an internal thread d is formed at the inner end to be screwed with the external thread c.

Then, one threaded member 6a is inserted into the through hole 8 of one side wall 4b to bring the flange portion a into contact with the outer surface of the side wall 4b, and the other threaded member 6b is inserted into the through hole 8 of the other side wall 4b. Then, a hexagonal wrench is engaged with the hexagonal hole b of both screw members 6a and 6b so that the flange portion a abuts against the outer surface of the side wall 4b, and the female and male screws c and d are screwed.
When the female and male threads c and d of the screwing members 6a and 6b are screwed together, the support member 3 is clamped by the left and right side walls 4b of the fitting member 4, and the belt mounting bracket K is firmly attached to the support member 3. can be fixed to

The fastener 6 is arranged at substantially the same height as the headed pin 5 and can abut on the rear surface of the support member 3 .
The headed pin 5 is fixed (welded) to substantially the center of the front surface of the fitting member 4 in the vertical direction and the horizontal direction, and can be hooked to the terminal fittings F provided at both ends of the belts B1 and B2. The hooked terminal fitting F can be prevented from coming off by the head 5a.

The first belt B1 and the second belt B2 are load tightening belts, each of which has a terminal metal fitting F attached to the end of each belt. Although an open hook type may be used for the terminal fittings F at both ends, a safety hook type is exemplified in the embodiment.
The multistage rack unit device 2A is assembled by fitting the fitting members 4 of the belt mounting brackets K to the left and right strut members 3 on the front side with the two rack units R placed on the ground, and fastening them to the rear portions. The tool 6 is inserted, and the belt fitting K is fixed to the support member 3 so that the headed pin 5 protrudes from the front side of the support member 3. - 特許庁

Then, the rear rail 12 on the upper stage and the rear part of the upper frame U on the lower stage are connected by a vertical connector P.
Then, the terminal fitting F at the lower end of the first belt B1 connected to the right upper head pin 5 is connected to the left lower head pin 5, and the lower end terminal of the second belt B2 connected to the left upper head pin 5 is connected. A metal fitting F is connected to a pin 5 with a right lower head, and a first belt B1 and a second belt B2 are installed in an X shape.

By stretching the two belts B1 and B2 in an X shape, it is possible to flexibly absorb the vertical vibration and horizontal deflection of the multi-level rack unit R, thereby protecting the multi-level rack unit R from being damaged or falling off. In addition, it is possible to prevent the cargo N from falling out of the cargo entrance (front opening Q) on the front surface of the rack unit R.
The belt mounting bracket K and the two belts B1 and B2 can also be arranged on the rear surface side and/or the left and right side surfaces of the multi-stage rack unit R. In addition, when the multi-level rack unit R has three or more levels, the belt mounting bracket K and the two belts B1 and B2 can be arranged according to the relationship between the upper level and the middle level and between the middle level and the lower level, or the middle level can be removed.
